【 摘 要 】

BackgroundEntomopathogens are pathogenic to insect pests. Several types of naturally occurring, viz. fungus, bacteria, viruses, and nematodes, infect a range of insect pests and help manage crop growth. They offer several advantages over chemical pesticides, including being precise, safe, and ecologically sustainable. Agricultural systems are streamlined, and changes to natural ecosystems occur. Viruses, bacteria are host-specific, while fungi have a greater host range, and they may infect both soil-dwelling and aboveground pests.Main bodyThe study highlights the current state of knowledge on entomopathogenic microorganisms (EM) (entomopathogenic fungi, nematodes, viruses, bacteria, etc.) as it relates to their current usage as biological pest management. It is essential to enhance our understanding of the ecology of EM and their role in nature to use a variety of biological control techniques against insect hosts. This article may help to comprehend their accomplishments in the significant field. Some recent researches indicated common patterns in interactions between insect pests and EM.ConclusionMore focus has been placed on the use of natural enemies like entomopathogens for pest control in recent years. EM expands possibilities for insect control. Eco-friendly alternatives to existing agricultural pesticides are being developed which are utilized to control insect pests and support agricultural sustainability.
